C6 Corvette

Chevrolet built the sixth-generation Corvette for nine model years. It opened for 2005 as a coupe and a convertible with a 400-horsepower LS2 V8, and by 2009 the family reached 638 horsepower in the supercharged ZR1.

What is the C6 Corvette?

The C6 Corvette is the sixth generation of the Chevrolet Corvette, covering the 2005 through 2013 model years and built in Bowling Green, Kentucky. It kept the front-engine, rear-drive, two-seat layout and added fixed headlamps, a shorter body and, over time, the Z06, ZR1, Grand Sport and 427 Convertible.

Production of the 2005 coupe began in the summer of 2004, and the convertible followed that fall. GM said it wanted a performance car that felt at home in almost any setting.

The family grew in steps: the 505-horsepower Z06 for 2006, the LS3 V8 for 2008, the supercharged ZR1 for 2009, the wide-body Grand Sport for 2010 and the 427 Convertible Collector Edition for 2013, the final year of the generation.

The C6 shared its basic chassis layout with the C5. Even with added safety features, weight-saving work left the car roughly 20 pounds from the weight of the 1997 Corvette, according to GM.

What changed from the C5 to the C6?

The C6 was 5 inches shorter and about 1 inch narrower than the C5, wore fixed headlamps for the first time since 1962 and cut drag to a 0.28 coefficient. Under the skin it kept the C5 layout: a hydroformed steel backbone with the transmission at the rear.

  1. Size

    Five inches came out of the length and about 1 inch out of the width, while the wheels grew to 18 inches in front and 19 inches at the rear.

  2. Headlamps

    Exposed headlamps returned to Corvette for the first time since 1962. GM said the fixed lamps cut weight, complexity and aerodynamic drag.

  3. Aerodynamics

    More than 400 hours of wind tunnel testing produced a 0.28 drag coefficient, which GM called the most aerodynamic Corvette to that point.

  4. Access

    Keyless Access swapped the mechanical door and hatch handles for solenoids and electronic actuators, which kept the body lines smooth.

  5. Roof panel

    The coupe kept its removable roof panel, now 15 percent larger and only 1 pound heavier, with the same structural stiffness as before.

  6. Rear design

    A tapered rear deck and fascia improved high-speed performance, finished with round taillamps and a center-exit exhaust.

Designers kept the round taillamps and the dual-cockpit cabin, and GM said the aim was to distill the passion of the mid-year Corvettes of 1963 to 1967.

The structure carried over in concept: hydroformed steel rails, cored composite floors, an enclosed center tunnel and an aluminum cockpit structure. GM redesigned the suspension from the cradles and control arms to the springs, dampers, stabilizer bars and steering gear.

What changed each year of the C6 Corvette?

GM changed the C6 almost every model year. The Z06 arrived for 2006, the LS3 engine for 2008, the ZR1 for 2009 and the Grand Sport for 2010, and the run closed in 2013 with the 427 Convertible and a 60th Anniversary package.

The final year brought the 427 Convertible Collector Edition with the 505-horsepower LS7 and a 60th Anniversary Design Package for every model. Black returned to the palette, joined by the new Night Race Blue Metallic.

How do the C6 Corvette models compare?

Five models shared the C6 platform by 2013. The coupe and convertible used the standard V8, the Grand Sport added a wide body and Z06-size brakes, the Z06 and 427 Convertible used the 505-horsepower LS7, and the ZR1 topped the range with 638 supercharged horsepower.

Every C6 was a two-seat car built in Bowling Green, and every one sent power through a rear-mounted transmission. What separated the models was the engine, the frame material and how much carbon fiber GM used.

What engines did the C6 Corvette use?

Four small-block V8s powered the C6: the 6.0L LS2 with 400 horsepower, the 6.2L LS3 with 430, the 7.0L LS7 with 505 and the supercharged 6.2L LS9 with 638. All four were overhead-valve engines with aluminum blocks.

The LS2 came from GM's Gen IV small-block family, and GM called it the most powerful standard small-block offered in a Corvette to that point. It used cylinder heads derived from the C5 Z06, a 10.9:1 compression ratio and exhaust manifolds 34 percent lighter than before.

The LS3 replaced it for 2008 with 6.2 liters, larger valves and heads based on the LS7 design. It made 430 horsepower and 424 lb-ft of torque, or 436 horsepower and 428 lb-ft with the optional dual-mode exhaust.

How was the LS7 different?

The LS7 brought the 427-cubic-inch displacement back to Corvette as a small-block. It used titanium connecting rods and intake valves, an 11.0:1 compression ratio, a 7,000 rpm redline and a dry-sump oiling system. GM said its connecting rods weighed 464 grams each.

The LS9 added a Roots-type supercharger with a four-lobe rotor design and an integrated charge cooler. It was built by hand at the GM Performance Build Center in Wixom, Michigan, and rated at 638 horsepower and 604 lb-ft of torque.

What transmissions did the C6 use?

A six-speed manual was offered on every C6, and it was the only choice in the Z06, ZR1 and 427 Convertible. The 2005 automatic was the four-speed 4L65-E. For 2006 GM replaced it with a six-speed paddle-shift automatic with Drive, Sport and Paddle Shift modes.

What made the C6 Z06 different?

The C6 Z06 was a different car under the skin. Launched for 2006, it paired the 505-horsepower LS7 with an aluminum frame, a magnesium engine cradle, carbon fiber fenders and a fixed roof, and it was 3 inches wider than the other models.

GM developed the Z06 alongside the C6.R race car. Earlier Z06 models, from the 1963 original to the C5 version, added suspension or engine upgrades to the standard Corvette. This one had its own body structure.

Aluminum frame, carbon fiber body

One-piece hydroformed aluminum rails replaced the steel frame, and GM later said the aluminum frame weighed nearly one-third less. The front fenders, front wheelhouses and floor panels were carbon fiber, and the floors used a balsa wood core. The battery moved to the rear to improve weight balance.

The LS7

The 7.0L LS7 made 505 horsepower at 6,300 rpm and 470 lb-ft of torque at 4,800 rpm. Red engine covers with black lettering marked it under the hood. For 2009 GM enlarged the dry-sump system from 8 quarts to 10.5.

Z07, CFZ and Z06 Carbon

For 2011 the Z07 Performance Package added Brembo ceramic brakes, Magnetic Ride Control and Michelin Pilot Sport 2 tires on 19-inch front and 20-inch rear wheels. The CFZ package added a carbon fiber splitter, rockers and roof panel. The Z06 Carbon limited edition combined both, and Chevrolet capped it at 500 cars.

Brakes, wheels and tires

The Z06 used 14-inch front rotors with six-piston calipers and 13.4-inch rear rotors with four-piston calipers. Its 18 x 9.5-inch front and 19 x 12-inch rear wheels carried 275/35ZR18 and 325/30ZR19 tires, which GM called the largest wheel-and-tire combination offered on a Corvette to that point.

GM listed the 2006 car at about 3,130 pounds. By 2009 it quoted 0 to 60 mph in 3.7 seconds, the quarter mile in 11.7 seconds at 125 mph and a 198 mph top speed.

What was the C6 Corvette ZR1?

The ZR1 was the top C6 model, sold from 2009 to 2013. Its supercharged 6.2L LS9 made 638 horsepower, and GM called it the most powerful and fastest car it had produced, with a top speed of 205 mph.

The ZR1 shared the aluminum frame of the Z06 and added more carbon fiber, including the roof panel. Only two options were offered at launch: chrome wheels and an upgraded interior package.

The cluster added a boost gauge and a 220 mph speedometer, and the head-up display showed boost as well. Sill plates and headrests carried the ZR1 logo.

The ZR1 weighed 3,324 pounds, used a twin-disc clutch and reached its top speed in sixth gear. Magnetic Selective Ride Control was standard. Performance Traction Management arrived for 2010, and the PDE package for 2012 added Michelin Pilot Sport Cup tires and a full-width rear spoiler.

At the Nürburgring, GM recorded 7:26.4 in 2008 and 7:19.63 with the 2012 car. GM noted that lap times there are unofficial.

What was the C6 Grand Sport?

The Grand Sport joined the C6 line for 2010 as a coupe and a convertible. It combined the 430-horsepower LS3 with wide-body styling, Z06-size brakes and wider wheels and tires, and it replaced the Z51 package.

Its 18 x 9.5-inch front and 19 x 12-inch rear wheels carried 275/35ZR18 and 325/30ZR19 tires, and its brakes matched the Z06: 14-inch front rotors with six-piston calipers and 13.4-inch rear rotors with four-piston calipers. GM quoted 0 to 60 mph in four seconds and 1 g on the skid pad.

Unlike the Z06, the Grand Sport kept a removable roof panel on coupes and offered the paddle-shift automatic. Coupes with the manual transmission added a dry-sump oiling system, a differential cooler and a rear-mounted battery for track use.

The name came from five race prototypes built in 1963 and a 1,000-car edition in 1996. An optional Heritage package added front fender hash marks in four colors. In its first year the Grand Sport made up about half of coupe sales and 70 percent of convertible sales.

What was the 2013 Corvette 427 Convertible?

The 427 Convertible Collector Edition was a 2013 model that put the 505-horsepower LS7 from the Z06 into a convertible for the first time. GM called it the fastest and most capable convertible in Corvette history to that point.

It combined the Z06 driveline and rear axle with a rear-mounted battery, standard Magnetic Selective Ride Control and ZR1-style Michelin tires on 19-inch front and 20-inch rear wheels. The raised hood, the fenders and the floor panels were carbon fiber, and a six-speed manual was the only transmission.

GM estimated a top speed above 190 mph and 1.04 g of lateral grip. Buyers could add an option to help build the LS7 for their own car.

How did C6 brakes, wheels and suspension differ by model?

Every C6 used short and long arm suspension with transverse composite leaf springs at both ends. Brakes and tires grew with each model, from 12.8-inch front rotors on the base car to 15.5-inch carbon-ceramic rotors on the ZR1.

Three suspension setups were offered at launch: the standard suspension, the Z51 Performance Package and F55 Magnetic Selective Ride Control, which used magneto-rheological dampers to adjust damping almost instantly. Anti-lock brakes, traction control and Active Handling were standard.

The C6 launched on Goodyear Extended Mobility run-flat tires, which removed the need for a spare. The Z06 moved to Goodyear F1 Supercar Gen 2 tires for 2011, and the ZR1 used Michelin Pilot Sport 2 tires developed for it.

What was the C6 Corvette interior like?

The C6 cabin followed Corvette's dual-cockpit theme in a smaller body with the same usable room. It launched with a keyless access and start system, and for the first time Corvette offered onboard navigation, on a 6.5-inch touch screen.

Passenger space stayed the same across the line: 52 cubic feet of interior volume, 38 inches of headroom and 43 inches of legroom. The coupe held 22 cubic feet of cargo, and the convertible held 11 cubic feet with the top up.

For 2006 GM fitted a smaller 370 mm three-spoke steering wheel and replaced the manual passenger air bag switch with a sensing system.

What special editions closed out the C6 Corvette?

GM closed the C6 run with a series of special editions: the 2011 Z06 Carbon, the 2012 Chevrolet Centennial Edition and the 2013 60th Anniversary Design Package. The 2013 427 Convertible Collector Edition was a separate model.

How did racing shape the C6 Corvette?

Racing ran through the C6 program. GM developed the Z06 alongside the C6.R race car, tested its fastest models at the Nürburgring, and Corvette Racing won the 2012 American Le Mans Series GT championship.

The link showed in the hardware. GM held the LS7 valve angles at 12 degrees based on its racing engines, and said the LS7 was co-developed with the GT1 engine that won at Le Mans. The 2011 Z06 Carbon carried graphics that marked 50 years of Le Mans racing.

  4. 2012

    Corvette Racing won the American Le Mans Series title in the production-based GT class, and Chevrolet took the Corvette Daytona Prototype to GRAND-AM.

The Nürburgring Nordschleife measures 12.9 miles with about 154 turns. GM noted that lap times there are unofficial and described the track as a way to validate its cars in the toughest conditions.

C5 vs C6 vs C7: where does the C6 sit?

The C6 was an evolution of the C5 and the bridge to the C7. It kept the C5 chassis layout in a shorter, narrower body, and its aluminum-frame Z06 and ZR1 set up the aluminum frame GM made standard on the 2014 C7.

GM replaced the retractable headlamps Corvette had used for 41 years, trimmed 5 inches from the length and held the weight to roughly 20 pounds from that of the 1997 C5.

What fuel economy did the C6 Corvette get?

EPA rated the LS3 Corvette with the manual transmission at 16 mpg city and 26 highway for 2008 through 2010. The Z06 was rated at 15 city and 24 highway in most years, and the supercharged ZR1 at 14 city and 20 or 21 highway.

These are the ratings listed on fueleconomy.gov. GM's own 2005 estimate for the manual car was 19 mpg city and 28 highway.

What recalls has NHTSA listed for the C6 Corvette?

NHTSA lists seven recall campaigns that include 2005 to 2013 Corvettes. Most cover the 2005 to 2007 cars, including a roof panel adhesive recall and a low-beam headlamp wiring recall. NHTSA shows no campaigns for the 2008, 2009, 2010 or 2013 model years.

A recall applies to specific vehicles, not to every car in a model year. Run the VIN through the NHTSA lookup before you buy a used C6, and ask for proof that any open recall was completed.

What should you check on a used C6 Corvette?

Start with the model year, because the engine and equipment changed during the run: the LS3 arrived for 2008, the Grand Sport for 2010 and new seats for 2012. Then confirm recall status by VIN and match the car to the right model.

What to confirm on a used C6

  • Engine by year: the 6.0L LS2 for 2005 to 2007, the 6.2L LS3 from 2008
  • Automatic by year: a four-speed for 2005, a six-speed paddle shift from 2006
  • Z06 and ZR1: fixed-roof coupes offered with a manual transmission only. A ZR1 carries its own VIN digit and a sequential build number
  • Grand Sport: coupes with the manual transmission have the dry-sump oil system, a differential cooler and a rear-mounted battery
  • Roof panel: 2005 to 2007 cars with a removable roof were recalled for roof panel adhesive, so ask for the completed recall record
  • Tires: the C6 was built for run-flat tires and carried no spare
  • Fuel: premium was recommended for the LS2 and LS3 and required for the LS7 and LS9
